“Quietism,” a mystical tradition of prayer in the Christian Orthodox Church. It is described in great detail in the Philokalia, a compilation of the writings on prayer and spiritual life by various saints. The Hesychasts were renunciants (usually monks) who believed that asceticism, detachment from the material world, submission to a teacher, prayer, and the perfect relaxation of the body and will would bring an inner stillness that would lead to the vision of the eternal light of God. The Prayer of the Heart (or the “Jesus Prayer”), taught in the Hridaya Silent Meditation Retreat, is an integral practice in Hesychasm. This prayer is the unceasing appeal to Jesus’s benevolence: “Lord Jesus Christ, Son of God, have mercy on me.”
